The Symbolism of Water Many works of literature use symbols to represent abstract ideas. One symbol that is commonly used is water. Water is a viable symbol because it is versatile. It can be used to represent many different ideals because water in itself is ever changing.
any milk or milk by-products, such as cheeses, ice cream, butter, etc is considered dairy. Soy milk is okay, as is rice milk. Eggs are considered dairy, but as they don't come from a cow, I am not sure that would be included in your excluding dairy--same goes for goat's milk and it's by-products.
For me, anything that contains casein, the protein found in milk, is considered a dairy item to be avoided. This includes cow's milk, butter, cheeses, and ice cream. This is not to be confused with lactose intolerance, which is an inability to digest lactose, the sugar found in milk and milk products.
